srozairne Ann nrsrnnsmo APPARATUS.

To au iti/0m it may cc neem Be it known that l, THoMAs T. BATHURST, a citizen of the United Statesresiding at Kansas City. inthe county oi Wyyandotte and State of Kansas, have invented neiv and useful Improvements in Storing and Dis# pensing Apparatus.- ot which the following is a specification. j

This invention relates to improvements in storing and dispensing apparatus, and more particularly to a device for storing and dispensing' volatile. or combustible liquids in which the liquid vis at all times surrounded by a heavier .non-coinbustibl-e liquid.'

lllhile this invention may have many uses it is primarily designed to provide a safe portable means lier storing" and dispensing gasolene or other volatile and combustible liquids. The giasolene is contained Within a container sublimi-ged and surrounded by a heavier non-combustible liquid. preferably water. having' a (ilispensing pipe leadingl 'from the top of the gasolene container so that the ,gasoleneis drawn oil at the top and the device so arranged that as the gasolene is drawn oil.vx thesurrouiuling water or hea vier noncoinbustible liquid enters at the bottoni of the container, the weight oli the water above the container forcing the gasolene out through the dispensing pipe without the use of a pump. This device is provided with gages by which the amount oi gasolene in the container is indicated, by which the specific gravity of the gasolene niay be deterrnined and by coinpaillson of the gages they will indicate whether er not the device has been tampered with and water substituted for gasolene that has been drawn ofi?.

While the preferred forn'is of this invention are illustrated upon the accompanying sheet of drawing, yet minor detail-changes may be inade without departing from the. scope thereof. l

. I and diameter rests upon the bottom of the outer container. The outer container is opened at the top, While the inner container 1s closed at the top and provided with one or more openings 8 in proximity to the bottom of the outer container', preferably in the side vof the inner container adjacent its bottom or in its bottom. A filling pipe 4 leads from .the top ci the inner container to a point above the top of the outer container Where it is connected by a gate valve 5 to a water supply pipe 6, preferably from .the city Water supply. The water supply preferably enterspthe valve at right `angles to the iilling pipe and the valve on the side -dianietrically opposite the iilling pipe is provided with a filling opening` 7 for the admission ot gasolene. A dispensing tube 8 leads from the top oiLl the inner container provided with a 'valve Sa within the -outer container. or from the fillingv pipe adjacent the top ot' the container, and passes through the walls ol the outer container preferably at right angles to the filling pipe and is provided. at its exterior with a discharge nozzle. The discharge nozzle preferably extends through one side of an indicator or gage box 9 secured to the outer side of the outer container, which bex extends from the top of the container to sonic distance below the discharge nozzle and is' provided With a door lO opening on a line with the dis' charge nozzle. Nithin the box is arranged a Water gage ll open at'thevtop and-connai-ente@ nen. e, reis.v

- nect'ed-at the bottom with the interior of the outer container at a level slightl above the top of the inner container. T e usual pet cock 12 on the bottoni of the gage glass holder will discharge through an opening in the bottoni of the hon. rllhe safety'rods 13 on each side of the gage glass are bent at right angles at the top, passed through the box and Wallet" the outer container and are secured thereto upon the inner side. The gage glass is provided with a movable indicator 14- c'omprising a horizontal band bent aboutI the 'front of the gage glass With the ends passing under and around the safety rods whereliy the indicator will be retained ln the desired position. The Water gage glass is preferably arranged'adjacent the' discharge neuf/.le leaving a space lo in the i ndicatcr of gage box for storing the longer gasoleoe gage glass l'xereinaiter described for 'piping'. p l.

Si gasolene gage. glass lf3 is arrai'iged prefu erably parallel with and attached to the illing pipe having a connection therewith at the bottom adjacent the top of the inner container and open at the top. The water gage' glass and the gasolene gage glass are graduated for the purposes of comparison as hereinalter described An overflow pipe 17 is arranged within the outer container along one side thereof passing between the outer and inner containers having an opening near the bottom of the outer container to a sewer drain and extending to the proper level near thei top of the outer containerB A by-pass 18 is provided between the overflow pipe and the filling pipe connected with a union, having a blind melting gasket i9. lt is preferable to arrange a, brace 20 from the filling pipe to the wall ot' the outer container which brace will act as a support for the gasolene gage glass and also for the stems 21 and 22 of a gasolene gage valve and' a dispensing valve in the dispensing pipe. The gasolene gage glass and the handles of the gasolene gage valve and dispensing valve preferably extend above the top of. the outer container. y

The top of the outer container is provided with a conical cover 23 having an opening in its top slightly larger than the filling pipe and a vertical opening in one side over the valve handles, which opening is provided with a hinged door 24. lt is preferable to arrange the indicator or gage box and vertical opening in the top, so that the doors of both the top and box may be secured by a single padlock.

The method of operation is to first close the dispensing valve and opcnthe gate valve, admit water through the filling pipe 4 iintil the water stands at a level above the dispensing tube 8. then open the dispensing valve and-allow the water to seek the level thereof. lClose the dispensing valve, open the gate valve admitting water to the vlillhig pipe until it reaches the level of the over flow pipe, then admit gasolcne while the ,water is running which `provides a'lneans tor screening the gasolene. The water will pass out the overflow pipe and the gasolene being lighter than the water will collect in the top of the inner container forcing the water below it through the apertures inthe bottom ofthe inner container. Admit water and gasolene until the filling pipe is 'full to overflowing with gasolene which insures a. full gasolene container without danger of letting gasolene into the water receptacle. When the water in the outer container seeks its level at the overflow, the gasolene in the filling pipe seeks its level at the top of the illingl pipe, thereby obviating the danger of overowing the inside container.

To dispense the gasolene 1t 1s only neces- -sary to open the dispensing valve as the weight' of the water above the inner 'conmeneer tainer will force the gasolene through the top of the container' down to the last drop, the water seeking its former level and thereby drawing o no water.- lt is to be noticed i that the water gage glass in the gage box is ot less length than the gasolene-gage glass attached to the lling pipe, the reason there'l of being that gasolene is lighterthan water. These two gage glasses are properly graduated so that the outer water gage glass is so graduated as to indicate by the level of the water in the outer container the amount of gasolenel drawn from the inner container. The gasolene gage glass is so graduated as to compare withy the water gage glass in such a manner that it can be easily distinguished s s to whether the tank is tampered with and also tell the specific gravity or" the gasolene The water gage glass is'graduated in gallons to indicate each gallon of gasolene that is drawn oli', as each gallon of gasolene drawn oli' causes the level of the water in the outer container to sink as the water enters through the bottom of the inner container taking the place of the gasolene removed, `d therefore the level ot the water in the water gage glass may be graduated to indicate the amount of gasolene drawn oli. The gasolene gage glass has corresponding graduations so that when the valve at the bottom of the gasolene gage is open it permits the gasolene to seek the level of the corresponding graduations which would indicate whether the apparatus' had been tampered with or not,

because ,should a gallon of gasolene be drawn oil and a gallon of water lsul)stituted 'the water level would be higher in the water gage glass than the corresponding graduations on the gasolene gage glass' at which the gasolene .would stand.

The inner gasolene container is made and originally tested to contain a certain known quantity of gasolene of th-e lowest commer? cial specific gravity, and the relation of the height of the overflow for the water in the outer container tothe filling pipe is such that when the container is filled with gasolene of highest commercial specific gravity the gasolene will overfilowv at the top of the filling pipe insuring that th'"`'inner container is` not flooded. Whena high grade f dof gasolene is used the filling pipe will overflow before the gasolene container -is filled.l

The relation! of the height of the overflow is such that there is a sucient amount oi :ateneo ii leneend substituting Water it will be iinm'ediately revealed/by comparing the two gages The outlet from the overflow pipe to the sewer is above the opening ot the inside container so that should the overflow pipe 'ne broken olf a Water seal would still be left.

' 'lo prevent freezing in cold weather a brine is used instead of water which can be readvilyinade by puttingsa'lt in the bottom of the outer container'. The outer container l and top cover are preferably provided with ,f an asbestos covering.

The 'fusible gasket Will melt at 125 degrees F. or any desired degree, so that should the temperature in the room be caused by any source to reach the deierniincd degree. the gasket would .melt and autonnitically discharge the gaso iene' from the container through the overtloiv pipe or otherwise to the sewer or suit ahle container in a safe place. When. the valve in the gzsolene gage open lor the purpose of making tests the air will enter through the top and permit the gasolone to seek it only necessary to blow down. the tube yind immediately close the valve leaving no gasolene to evaporate or become wasted. According to the location of the device, it may be desirable to insert a valve Q in the Water pipe 5 between the filling valve and source of supply, which may be regulated to permit any desired supply of water While filling, thus insurings a sul'licient balance for the. gasolene.

The device shown in Fie l is a portable dispensing,` apparatus for a garage' or other building. 4l and 5 illustrate the application of this invention to the gaso- Jlene tank of an automobile .in which the outer tank or container may be of any desired shape it illustrated as being oval in cross-section, which is the popular form at the present tiinejfor automobile gasolene tanks. The gasolene container 3l is preferably llat on the top with its sides corresponding in shape to the shape of the outer container wall, and preferably held above the bottoniv of the outer container by rigid supports ln this torni it is preterahleto provide a single central ope/nini;T 33 in the gasolene tank upon the under side, The filling pipe 34 through which both Water and g: solene enter entende from the top ot' the gasolene container through the top of the outer container Wall, and is preferablyv provided with its level. lli/l hen the test is completed .dispensed the tank sinks.

and in this particular instancea gasolenepipe 35 leading at right anglesl thereto in proximity with the top of the gasolene tank through the outer container Wall` to the carbureter. The outer container is provided with a pet cock 36 upon its up per side leading to an overflow. lt 1s preferable that the gasolene pipe leading to the carburetor be provided with ar `valve 37' on the interior of the outer container having a stem 35% passing through a stulling box in the walls thereof. The relation of the inneiI and outer containers to each other is such that when the outer'container is filled with lwater and the inner container lilled with gusolene there is a sufficient amount of lwater in the outer container to deliver all of thel gasolene from the inner container. The saine gages as shovvn in Fig. l will be applied to this container as Well.

lt' preferable the gasolene gage glass may be arranged on the outside of the outer Acontainer in the same housing with the water gage glass closed with a valve on the inside of the outer container. lf preferred a rotary pressure gage which accurately registers light pressures may be used instead ot the glass tube, obtaining the sanne results by so doing, llilhile in the form illustrated the inner grasolene container is shown statiouar with a chauve of water level as the i O'asolene is dispensed, the same result could oe obtained by' a movable tank for containing the gasolene in the water so that as the tank is lled it rises and as the gasolene lt desired the filling tube .can be incased in a water jacket so that the gasolene will at all times be entirely surrounded by water, or-the lilling pipe 'may be so constructed that it can be telescoped beneath the surface ot the water after filling.
